Question

What is the center of the circle represented by this equation? x^2 + (y + 9)^2 = 25 A) (3, 5) B) (0, 25) C) (9, 25) D) (0, -9)

Answer 1

the equation of the circle is in form:

(x-h)² + (y-k)² = r²

(h,k) are the center and r is the radius.

So from the given equation we can see that the center is at (0,-9).

Hope this helps :)
